Colorectal cancer typically develops from adenomatous polyps—small, benign growths in the lining of the colon or rectum. Over time, some of these polyps can become cancerous due to a combination of genetic and environmental factors.

Risk factors include:

Age: Most cases are diagnosed in individuals over 50, although rates among younger adults are increasing.
Diet: High consumption of processed meats, low fiber intake, and obesity are linked to higher risks.
Family History: A family history of CRC or certain genetic conditions, like Lynch syndrome, can increase risk.
Lifestyle: Alcohol consumption, smoking, and lack of physical activity are also contributing
